Ossur Gameday Ankle Braces are made to get you back up and running. This brace is even easy to lace up without shoe removal! Figure 8 straps give inversion/ eversion support without the fuss of athletic tape. It is perfect for athletes to deal with nagging sprains, strains, and chronic instability. To figure sizing, measure the ankle diameter diagonal to the floor, over the base of the heel, and across the ankle bone.
